Abstract
Regional development through collaborative creation is an urgent issue. However, there is no indigenous research in Japan.
This paper investigates the relationship between regional development and entrepreneurs based on the concept of "Ba". As a result, we concluded that the familiar orthodox concept of "Sou" social system is highly valid. In addition, it was clarified that new encounters are necessary for innovation, but that the logic of Alternative cannot explain such encounters. The Japanese concepts of "un" "Guzen" "Engi" "Kaikoh" can explain these encounters. For the creation of local communities, it is essential to form a place of “Yozho”circulation, based on an Brotherhood economics.
